Just getting back to completing my GTR after yet another layoff.
Anyways to the question, I periodically fire up the engine to keep everything nicely lubricated. Now over the past 5 years or so I've got through 2 Odyssey PC625 batteries. The last one was purchased a couple of years ago and just doesn't hold charge, even when not connected up.
So I know its not the best way to treat a battery, but surely it should be better than that.
Before I decide what to buy, has anyone else had problems with these batteries or have any advice.

I'm pretty sure, the reported damage was, supposedly, caused by trickle charging, however as you said the sophisticated chargers we have now just keep the batteries conditioned.
The first PC625 I had lasted a couple of years before giving up the ghost. I made the mistake of leaving it connected on the car and apparently the alternator always draws a slight current, plus I found out subsequently my alternator was knackered. So perhaps a combination of faults and my oversight caused it to die.
The second battery however has only ever been connected when starting the car, with a new alternator fitted. The odyssey blurb states a fully charged battery will hold its charge for up to 2 years when in storage. Hmmmm, mine doesn't.
So am I just unlucky? What are the batteries of choice?

David . by the way the pc 925 will fit in the Ultima with little issue. Nearly same money, always better to have more amps in the battery if practical. My P.C. 925 just sat for a month with no issue at all, but I agree with the folks above a battery tender that cycles on and off to keep the battery topped off is best. Lee
Thanks Lee,I found with both batteries I had, that if my car didn't start within 6 to 8 goes of 10sec cranking then the battery was flat. I'm definitely investing in a ctek charger.

Your car should start first time if it is an LS engine (I couldn't find details in your profile).
The Factory recommended battery is at it's limit with a large capacity engine, so you do need to keep it topped up. I increased the size of my battery to a red top 60, with no issues since.
No battery likes to sit, so charging and discharging it regularly is the only way to keep it in good condition.

My engine is an sbc, in fact it's the one from the factory demo car (640). The battery was what,at the time was recommended by the factory.
As has been suggested, I've always felt the battery has been at it's limit and as I've said is quickly depleted. Sounds as though most are opting for a higher capacity battery.
